Getting a blank screen with "Internal Server Error" while using the web interface. Only solution is to restart tomcat from CLI.
It looks like this issue has been brought up many times before. I still have this happen way too often. Multiple firewalls, different models all on v18 MR3 or mostly MR4 now. Just had it happen again on an XG210 while doing packet capture.
I read there was a fix for the v17.5 version at some point!? Is Sophos Support aware of this bug in v18?
Thank you for contacting the Sophos Community!
There’s a known issue investigated and fixed on 18.0 MR5 under NC-64984 this relates to the issue happening when refreshing a packet capture…

If you haven't I would recommend you to open a case with Support to have this issue logged and share the Case ID.
If you are able to reproduce the issue, try putting CSC in debug mode
# csc custom debug
To turn off debugging run the same command
And provide the output of the csc.log and tomcat.log and df -h
The Problem is still there.
This issue is resolved in MR5, MR5 isn’t released yet, it’s coming out this week.
MR5 is available since April 5 https://community.sophos.com/sophos-xg-firewall/b/blog/posts/xg-firewall-v18-mr5-is-now-available
