Issue

File system  restarts with the following panic:

ERROR: MSG-INTRNL-00001: PANIC: ddr/repl/lrepl_client.c: mrepl_send_file: 13507: repl ctx 4:29: mrepl_send_file: repl client is closing the stream when server still has pending seg request.

This issue is because of AMS and VSR both enabled at the same time causing memory leakage.


Cause



Solution

  1. Update  to DDOS 6.1.1.10

Workaround

There is a workaroud to be applied to data domain to make it stable and to avoid DDFS panic every time, which is happening due to a known bug #204102 in DDOS 6.0.2.x, and is fixed in 6.1.1.10.
