Products

• ISG Proxy

Issue/Introduction

ProxySG crashed/rebooted with the following exception.

Version: 6.7.5.19.277122
HW Exception: 0xe
SW Exception: 0x0
Process Group: PG_ACCESS_LOG
Process: Process "sshc.worker" in "libsshd.exe.so" at .text+0x29ea36

Environment

SGOS Release : 6.7.5.19

ProxySG configured to push logs to Remote log server via SCP Protocol

Cause

External Log Server was experiencing an unrelated resource issue and was becoming unreachable by ProxySG.

SSH is not in a proper state to push out an error message. 

Need to add null pointer checks in code.

Resolution

Fix has been checked into SGOS version 6.7.5.21 and 7.3.12.1 due to be released early 2023. 
Should be able to search for the defect id "SG-33195" in the release notes once these versions are public.

Workaround is to resolve the  cause of the unresponsivive remote log server, or
Use another protocol other than scp to upload Access_logs to remote Log Server.
