[leafnode-list] Memory leak (Was: Limiting leafnode run time and/or memory usage?)
I have more information about this issue (see below).
There appears to be a significant memory leak in leafnode-20041215a.
I'm running this in a local-group-only configuration. Every time I
issue a "group local.newsgroup" command from within an nntp session,
the leafnode process grabs around 320,000 bytes of memory that it
never releases. This is consistent: each and every time I issue that
command, the memory footprint of the leafnode process increases by
this amount. This has continued all the way up to 256 meg.
I can hack my way around this problem by putting the following line
within the xinetd "service" block quoted at the bottom of this
However, this is not an optimal solution, because it could cause
leafnode to die in the middle of processing a command, thereby
causing users to receive error messages. The ideal solution is to
fix the memory leak, of course.
I thought I'd report this here. I'll try to find this leak, but it
might take me a while because it's been years since I have dug
through the leafnode code. Someone else with more familiarity with
the source to leafnode would probably be able to diagnose and fix
this more quickly.
