Slammed some beers and went back to town. Built Radiance on a Debian Buster VM, and had the same issue. Fiddled around with the radiance.conf some more, bumped the mysql_timeout to 120, and this looks to have resolved the issue.

Does the log not provide any hints?

My suspicion would be it's spinning round the flush loop very quickly and isn't able to flush it to the DB.

With Radiance is running inside of gdb, compiled with the jemalloc and debug flags, I'm not experiencing crashes, no stalled torrent / peer queue, and the CPU usage remains normal.

It looks like the torrent flush isn't actually flushing to the DB, how big is your connection pool for the DB?

If you use addr2line on the crash addresses where does it point you?

poorplanet commented on September 1, 2024

I might be the village idiot here, but by connection pool, are you asking about my MySQL connection settings?

addr2line breaks down the following:

poorplanet commented on September 1, 2024

My Boost is currently version 1.55. I'm guessing it's too old and updating to 1.66 now.

from radiance.

Empornium commented on September 1, 2024

By connection pool I meant how many connections you had configured radiance to use, if you left it at default then it should be 8, which is fine I think.

We run on Debian Buster, which appears to have boost version 1.67 so 1.66 should work fine. 1.55 is definitely the oldest boost it'll run on.

Empornium commented on September 1, 2024

Glad you got it fixed.
