CSV report download is not possible. SSB is showing a " Internal lock error; lock='ps_logspace_dynamic_columns_cache_xxxxxxxxxxxxxxxxxxxxxxxxxx', holder='SYSTEM@xcb' " error message.
The mentioned logspace is locked by the system.
There is a lock directory under /opt/ssb/var/lock directory. That lock directory contains all the locked files / logspaces. The content of the lock directory can be deleted (# rm /opt/ssb/var/lock/ *) to resolve this issue.
Also, it is a good resolution to just remove the specific lock file that refers to the logspace / file in the lock directory, to be able to have the respective logspace / file unlocked.
