[rt-users] segmentation fault

[José Luis Gordillo Ruiz]

Hi,

My RT 4.2 instance is not working properly. Sometimes it gets errors in creating tickets or sending mails. Logs show segmentation faults of httpd. On of the cores I could get
shows that the segmentation happens in malloc

This RT is running in a virtual machine. At the beginning, it had 512 MB of RAM and was very slow when several sessions were open. Then we increased the RAM to 1 GB. The speed is now good but this strange behavior started.

Any ideas?
