Numerous problems after drive maxed out

Postby ryan2368 on Tue Jun 20, 2017 3:12 pm

We have a Zend 8.5.7 running on Windows 2012. Over the weekend, something happened (we are still trying to track down what) which caused the Devbar.db files to fill the drive up. We stopped services, deleted the devbar.db, and let it recreate itself. The server came back up, but now I cannot change the monitoring. I keep getting Database locked error 5. Looking through the logs I found some semaphore errors:

[DataCache Log 20.06.2017 05:38:40 ERROR] Could not initialize Zend Data Cache: Fatal error: failed to allocate semaphore.
[DataCache Log 20.06.2017 06:23:13 ERROR] Could not initialize Zend Data Cache: Fatal error: failed to allocate semaphore.

Can't seem to figure out what is going on.

Could you please open a support ticket in order for our support to handle the case directly with you ? To do so, please go to https://support.roguewave.com (register if you don't have a user on our new support system, and request an invite to the support portal).
Once you're logged in you will have top navbar links to create a case.
From there, open a support case, and attach a support tool dump (by running /usr/local/zend/bin/support_tool.sh).
We will proceed within the support case after reviewing all the logs.
