[Dxspider-support] Troubleshooting direction needed

[Dale Harwood]

Greetings all!

We have 2 clusters that I recently upgraded. Both ran without error 
before the upgrade.
Information on both systems:
Intel hardware
VmWare ESX 5.5
Ubuntu Server 22.04 LTS
DxSpider: System 1 = 1.57 build 491 / System 2 = 1.57 build 516

System 1 runs without issue.
System 2, Spider restarts constantly. It may run 10 minutes, it may run 
an hour. It has failed since the initial upgrade, and has had at least 3 
build revision updates since the initial install, all failing the same.
System 1 is the backup for system 2, and lives at my location, and I 
have hands on access to it.
System 2, the main system, resides at another location and I am having 
to troubleshoot it remotely.(have files sent to me etc..)
The hardware seems to be fine as VmWare will run for weeks without 
error, as does the guest operating system (Ubuntu). The only issue is 
Spider restarting.

Which logs should I start looking in, and what should I be looking for?

I am proficient at the hardware, VmWare, and the OS, but Spider has run 
without fail for the past decade, therefore I have never had to dig into 
it, and will claim to be ignorant as far as troubleshooting it (-:

Any pointers would be appreciated so I can get log files headed my way 
for review.

Thanks in advance!
