Subject [jira] Commented: (AXIS2C-858) Apache runs out of memory and crashes with a simple mtom service test run in a loop
Date Thu, 03 Jan 2008 13:03:38 GMT


Manjula Peiris commented on AXIS2C-858:

Hi Subra,

We have done some fixes regarding the issue. And with those fixes and with following configurations
in my httpd.conf I was able to run the mtom sample in a loop concurrently from 6 shells without
any issue.

LoadModule axis2_module /usr/local/apache2/modules/
Axis2RepoPath /home/manjula/axis2/c/deploy
Axis2LogFile /tmp/axis2.log
Axis2MaxLogFileSize 10
Axis2LogLevel crit
<Location /axis2>
        SetHandler axis2_module

Remember I am using Apache2.6 and Axis2 from current svn [1]. (Revision 608428)

Please also note that I set the client log level also to log level critical (as in the server),
because it is the typical production environment scenario. Can you please try with the latest
svn and comment on the issue ?.

> I have a simple mtom service written in Axis2/C which receives requests from clients
with attachments. I wrote a client to consume this service and ran a test in a loop with 4
mb attachments. I noticed that the apache server ran out of memory and became very unresponsive
after about 45 mins and then core dumped. The server response seemed to improve after some
of the threads/processes died due to lack of memory and new threads were created to process
the request.
