We joined EAP - Cryptoguard for Mac, after new agent was deployed from central we started to observe random crashes on some machines. The OS freezes and then Mac reboots.
I was wondering if someone already seen anything similar?
When we look into log we can see reference to SophosCryptoGuard:

We captured SDU logs from two machines and decided to leave the program on most of stations, now it's running only on one unit.
After uninstalling agent with crypto guard problem wasn't observed on those machines. Only one of those machines is running FileVault, so I don't suppose it's a matter of conflict with encryption software.
Thanks,
