I had this problem twice. If nyx is running more than 1-2 days, it starts to consume more resources (I think, it is RAM). Finally, system becomes very slow and unresponsive until nyx (2.0.4 installed using python3-pip) is killed by system OOM-killer. This is what I see in /var/log/messages after that:

Purging GPU memory, 0 bytes freed, XXXXXXX bytes still pinned.
nyx invoked oom-killer: gfp_mask=0x201da, order=0, oom_score_adj=0
nyx cpuset=/ mems_allowed=0

Damn, that's no bueno. Please run 'nyx --debug' and add the log (redacted of any data you feel is private) to this ticket. If this takes days to manifest then the log will probably be too large, so simply include the start and end of it.

run nyx --debug and add the log (redacted of any data you feel is private) to this ticket

OK. I'll try it.

I am sorry for off-topic. When I create tickets, for the component "Core Tor/Nyx" I can select only Tor version, but I expect it should be Nyx version instead. If I am right, that menu should be fixed in trac interface itself.

Hi wagon. The version field is unused for nyx tickets. The only fields I care about are listed on...

Resolution: not a bug
Status: needs_informationclosed

Hi wagon, think I'm gonna close this one. Feel free to reopen if you're still encountering memory leaks and have a debug log for when it occurs.

OK. It is hungry on RAM anyway, but it is not easy to demonstrate where and why this problem arises.

Note: See TracTickets for help on using tickets.
