Subject SSL results in segmentation fault
Date Tue, 30 Sep 2014 07:14:20 GMT
Hello !

I'm configuring ATS as a reverse proxy and I need SSL support.

ATS runs on OpenVZ on Debian. It's the version 5.0.1 installed from 
backport packages.

ATS works fine, SSL too. But after a while SSL makes ATS crash.

In manager.log I found that there is a segmentation fault:

[Sep 29 16:08:33.020] Manager {0xb6fb76d0} ERROR: 
[LocalManager::pollMgmtProcessServer] Server Process terminated due to 
Sig 11: Segmentation fault
[Sep 29 16:08:33.021] Manager {0xb6fb76d0} ERROR: [Alarms::signalAlarm] 
Server Process was reset
[Sep 29 16:08:34.041] Manager {0xb6fb76d0} NOTE:

[Sep 29 16:08:34.049] Manager {0xb6fb76d0} NOTE: [Alarms::signalAlarm] 
Server Process born

Here is a dump of the syslog when crashing:

Any idea where to look for to solve this problem ?

Thanks a lot !
