Hi Mladen,

We have upgraded to Solaris 11.4 and relinked the Oracle homes couple of months ago.

As the system call nanosleep hangs, it should be an OS issue:

pstack 14583
14583: ora_vktm_DB
00007fff93c76eba nanosleep (7fffbfffc7d0, 7fffbfffc7e0) 00000000072f3e9a sltrusleep () + 6a

0000000007771e34 ???????? ()

truss -f -p 14583
14583: nanosleep(0x7FFFBFFFC7D0, 0x7FFFBFFFC7E0) (sleeping...)

In the meantime, we have a suspect: TimeKeeper. That’s a network time sync software installed by sysadmin to fulfill some legal requirements. We’re going to switch it off on the test server and observe.

Best regards,

Nenad, this maybe silly: have you recently done a Solaris upgrade? For instance to 11.4? If that is the case you may need to relink your Oracle home. That might fix the problem. Regards
