Ubuntu :: Diagnose Memory Peak - Server Crash
Dec 15, 2010My server crashed last week and I'm trying to diagnose why. /var/log/messages contains the following error messages, which indicate that the server's memory peaked. I would like to discover what process caused the memory peak. Being that "httpd invoked oom-killer", can I conclude that httpd was the cause of the memory peak?

Server :: Memory Peak Caused Server Crash - Data Interpretation?
Dec 16, 2010Last week my server crashed. I'm trying to diagnose the cause.
This is the relevant error message in /var/log/messages:
Code:
I'm assuming that I can conclude, then, that apache/httpd was the cause of the memory leak?
Next, I've been tracking my memory usage. Using top, this is an average memory load level for my server:
Code:
I'd like to confirm if my understanding of this data is correct, because Plesk indicates that my memory usage is only 50% or less. (Though I have read a number of reports indicating that Plesk's measurements are frequently wrong.)
Top says: Of the 2,073,156K total memory, 1,982,572K (95.63%) is being used, 90,584K (4.37%) is free. Of that sum, 421,948K (20.35%) are being used as buffers. Additionally, of the 2,096,472K of Swap, 60K is used, and 887,700K (42.34%) is cached.
My questions: Is my memory actually being 95% used? Or is the buffered quantity (20.35%) not a use of physical/virtual memory? (i.e. is it disk usage?) Does the amount of cached Swap influence the percentage of physical/virtual memory being used?
In other words, who is correct? Plesk says I'm using 40-50% of my memory, whereas top says 85-95%.
General :: Ubuntu - Memory Full, Process Memory Usage Doesn't Add Up In Top?
Mar 18, 2011I have a computer with 16GB of ram. At the moment, top shows all the RAM is taken, (NOT by cache), but the RAM used by the various processes is very far from 16GB.I have seen this problem several times, but I don't understand what is happening.My only remedy so far has been to reboot the machine.

General :: [Redhat 5.5] Unable To Access Network From An Oracle-started Process?
Jun 9, 2011We have a Oracle 11.2 database running on Red Hat 5.5. The database have a scheduled job to fetch some files from another server using ftp, and herein lies the problem.he job runs a pl/sql that runs the function in an (by us compiled) external libraryThe ftp-functionality itself is done by using libncftp and it's API's.The process starts correctly, but then trying to login to the actual ftp host, ncftp only reports "Unknown username/password" (which is not the case).I have the exact same code in an executable and when run from an interactive shell, it works fine.So the only thing I can come up with, is there are differences when the process is started by Oracle, rather then being ordinary" process.And I am stuck.If there are any environment variables, paths etc missing when running the extproc-process, how do I find out which?Because the real problem is NOT wrong user or password.

View 3 Replies View RelatedGeneral :: Calculating Process Memory Usage?
May 13, 2010What originally seemed like an easy thing to calculate has given me a big headache. Perhaps someone can help me with my issue. I am trying to find, in particular, how much memory certain application processes are taking. The process always is the same name, main_server, but with an argument to tell it what to do when running as a daemon.
When running the following command against all "main_server" processes, it produces a result in megabytes based on the output of the rss field in 'ps'.
Code:
CALC=0
for ea in
`ps -e -orss=,args= |
sort -b -k1,1n |
pr -TW$COLUMNS |
grep main_server |
grep -v "grep main_server" |
[Code]...
Currently I am left scratching my head. For capacity planning purposes, it would be nice to know how many more 'main_server' processes could run on the system without causing it to swap. Knowing the buffer and cache usage will go down as running processes demand more memory, I prefer to look at the free memory excluding cache and buffers. However, since 'ps' is reporting the processes are using more memory than free reports is in use without those things, I have no way to know how many more processes the system can support. I played around with different fields in 'ps', such as vsize, size, etc, but with no luck in matching up any numbers.
