                 Summary: On arm: hangs with 0% CPU until I strace it

The arm version of mldonkey-server reliably hangs a few minutes after I start
it. This applies to the original debian testing version, as well as 2.7.3-2
sources manually compiled on sarge. It does not apply to version 2.5.28.

When it hangs, its CPU usage stays at 0% and it fails to respond to any
connection attempts to ports 4000 and 4080 from localhost as well as the

I can easliy wake it up again by doing an "strace -p pid". This pid is not
$((cat /var/run/mldonkey/ but rather the pid of the parent mlnet
process. In the following pstree example this would be 14062.

|                        |-logger(14066)
|                        `-mlnet(14062)---mlnet(14067)-+-mlnet(14068)
|                                                      `-mlnet(14069)

Once strace starts I can easily stop it again and mldonkey will run for
another few minutes, until this situation occurs again.

I would be happy to deliver any further troubleshooting information to help
you take this challenge. It seems to occur only on my arm machine, not i386.
I'm not sure if it applies to all arms or only my Linksys NSLU2.
