I am using libevent 1.1a in our product. We have ever ported our product
from 32-bit Solaris to 64-bit Solaris,
that time I did not make any change to libevent source code, for from my
point of view, libevent is safe for 64-bit porting.
The first question I would like to confirm is, whether libevent pass 64-bit
Solaris environment test?
The second problem is, our tester came across the following problem when he
run our product with high call load on 64-bit Solaris environment.
Assertion failed: events[i].fd < devpollop->nfds, file
/vobs/css/siptrans/contrib/libevent/src/devpoll.c, line 271.
I can not figure out what caused such failure, appreciate your help.
Thanks a lot,
Liang
