Package: squid Version: 4.6-1+deb10u1 Severity: normal Dear Maintainer,
* What led up to the situation? Listen to an audio stream over the Squid proxy * What exactly did you do (or not do) that was effective (or ineffective)? Listening to audio streams using Parole on the same host as the Squid proxy * What was the outcome of this action? After ten or fifteen minutes of listening to an audio stream the Squid proxy crashes and restarts itself * What outcome did you expect instead? Working Squid proxy while listening to audio streams in current Debian/testing I discovered that listening to audio streams over the Squid network proxy using Parole on the same host let's Squid crash after ten or fifteen minutes of having the audio stream connection alive. Due to Squid crashes and restarts itself as seen in the Syslog all active network connections are dropped. That's how it came to my attention. I found the corresponding error message in /var/log/syslog and is as follows: Nov 10 05:01:14 g6 squid[27759]: assertion failed: stmem.cc:98: "lowestOffset () <= target_offset" Nov 10 05:01:14 g6 squid[2309]: Squid Parent: squid-1 process 27759 exited due to signal 6 with status 0 After this message Squid exists and starts up again. This bug is affecting the Debian version 4.6-1+deb10u1 of Squid.

In all other use cases besides audio streams I could not find any error or bugs. It just happens by listening to an audio stream with Parole over the Squid network proxy.
