Try recompiling your eggdrop with debugging enabled (make debug; make install), and make sure your shell is set up to do a coredump

Code: Select all

ulimit -c 10240

Then start your eggdrop again, and try to reproduce the error.
If that succeeds, grap the generated coredump, and follow the instructions in the bug report document (doc/BUG-REPORT), especially section 4.8.

That should hopefully provide some details where the memory-leak is located.

1.6.20 and libcrypto/libssl? You're using the horrible ssl patch for .20 despite of the numerous warnings in this forum against doing so. I'll pray for your soul but there's not much hope.

[Fire-Fox]

I have removed ssl and running without... for now

[pseudo]

Use 1.8 from cvs. If you could afford running a 3rd party patch, you can also afford using the official development code.

I have a similar error
tried with 1.6.20 1.8 and 1.9

phoenixpb, you face a different error and it's very likely to be the same one that's resolved here: http://forum.egghelp.org/viewtopic.php?p=97173#97173
