[LU-1418] (osc_lock.c:1099:osc_lock_enqueue_wait()) DEADLOCK POSSIBLE! - too many

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.3.0, Lustre 2.1.3
• Severity: 3
• Assignee: Oleg Drokin
• Reporter: Alexander Boyko

Description

The console log contains 100's of "DEADLOCK POSSIBLE!" errors, followed by debug data and a stack trace. The messages sound like something is seriously wrong, but there's no sign that a deadlock has actually occurred. To the contrary, evidence indicates that the app continues executing and completes successfully.
