Hello all,
I'm looking for some help with a significant issue I have.
Problem: About 60% of the time, whenever I login to my site through wp-admin, the site breaks. I get an "error 324" from chrome and "the connection was reset" in firefox.
To resolve this, I have to ssh into my server and restart the apache http server. After this, everything is fine until I am required to re-login back to my wordpress backend.
Server Details:
Amazon EC2 Instance, M1 Medium. AMI Details: bitnami-wordpress-3.4.1-0-linux-ubuntu-12.04-x86_64-ebs (ami-745af71d) php version: 5.3.14 with Suhosin-Patch (cli) mysql version: 5.5.21
Data
A screenshot of the error_log:
The main culprit seems to be a combination of these lines:
[Tue Dec 04 03:43:57 2012] [notice] child pid 10729 exit signal Segmentation fault (11)
[Tue Dec 04 03:43:57 2012] [notice] caught SIGTERM, shutting down
The "Segmentation Fault" seems to be causing the problem, but I don't know what is the exact issue.
Possible Solutions.
A potential problem is that the wordpress backend keeps asking for more memory, and it could be causing a buffer overflow, leading to the segmentation faults.
Here is a screenshot of the wordpress complaint:
Which makes no sense, because I have already changed the wp-config file to increase memory size:
And I have also modified php.ini to increase memory available via the php.ini file.
If I check how much memory is available on the server, it properly corresponds to the M1 memory size of 3.4GB of mem available:
Another possible solution
As per this previous discussion, there may be some sort of mismatch in mysql versions when I migrated the data. I will work on this thread to see if it solves it.
Any help would be greatly appreciated!
