[Sks-devel] Stack overflow

[Olaf Gellert]

Hi all,

has anyone else problems with Stack oveflows in SKS?

I get stack overflows after reconciliation attempts
and SKS always stops with a stack overflow if I try
-initial_stat:

pgpkeys:/usr/local/sks # ./bin/sks.bc db -initial_stat
Fatal error: exception Stack_overflow

Auszug aus log.recon:
2004-03-01 10:42:52 Beginning recon as server, client: <ADDR_INET 
65.57.232.167:46818>
2004-03-01 10:42:52 Joining reconciliation
2004-03-01 10:50:38 Reconciliation complete
2004-03-01 10:50:40 <reconciliation handler> error in callback.: Stack overflow
2004-03-01 10:50:41 Added 2 hash-updates. Caught up to 1078134510.656999

I do not get these errors if I do not run sks.bc but
just sks. So maybe a problem related to ocaml? Hmmm... 

I do not know if this has something to do with it, but
I wonder, why sks.bc is linked with libpthread.so, while
sks is not...

Regards, Olaf

P.S.: This is the regarding output of strace when running
sks.bc db -initial_stat:
