We are running OCUM 9.5P1 on CentOS and all of a sudden we get the following errors after login:

It seems like a problem with the MySQL-DB ...

any suggestions where to look further and how to proceed are welcome.

Thank you all

Hi there! I agree that it does look like a problem talking to the MySQL DB - because this is essentially troubleshooting a Linux system, the best option is probably to open a support case and work with our specialist support teams in troubleshooting this.

Finally I found a older backup and was able to restore that.

OCUM seems to work fine again.

Thx anyway for your suggestion.

best regards
