Re: lftp process is getting stuck, eating 100% CPU

Hey,

Here is a new gdb backtrace for another stuck lftp process. This time  
lftp was compiled with the debugging option:

#0  0x0000000000449b5a in strcmp ()
#1  0x0000000000477c63 in ?? ()
#2  0x000000000043aedc in strcmp ()
#3  0x000000000047cdbc in ?? ()
#4  0x000000000047e419 in ?? ()
#5  0x000000000043848e in strcmp ()
#6  0x000000000040b22c in strcmp ()
#7  0x000000000040801c in strcmp ()
#8  0x00000036c781d974 in __libc_start_main () from /lib64/libc.so.6
#9  0x0000000000407609 in strcmp ()
#10 0x00007fffa24d4d68 in ?? ()
#11 0x0000000000000000 in ?? ()

Any ideas?

Thanks,
Ilya Sabanin

Lately we started experiencing problems with lftp. Once in a while an
lftp process is getting stuck in a middle of deployment, eating 100%

we've got:

Please compile lftp with debug info (configure --with-debug).
