[tpop3d-discuss] open sockets...

Chris & Prune-

First of all- I want to say a big thanks for all your help in
implementing DARC, and in addressing the segfault on incorrect password
issue.

It looks like there is one issue that I see- and I believe it's a
"solaris" ism as I haven't seen much about the issue...

I have a system (my "semi-production" system)  which has 3 regular
users. Doing an lsof shows 241 open tpop3d connections in either
CLOSE_WAIT (63) or ESTABLISHED (177). These have been open for quite
awhile (hours).

This seems quite high, and I would believe that tpop isn't releasing the
connections to the ldap server. Some output:

tpop3d     418     root  236u  IPv4 0x30001500e10     0t697    TCP
mail:33263->mail:ldap             
 (ESTABLISHED)
tpop3d     418     root  237u  IPv4 0x30001500050     0t792    TCP
mail:33271->mail:ldap             
 (ESTABLISHED)
tpop3d     418     root  238u  IPv4 0x3000155be60     0t697    TCP
mail:33272->mail:ldap             
 (ESTABLISHED)
tpop3d     418     root  239u  IPv4 0x3000150e908     0t792    TCP
mail:33275->mail:ldap             
 (ESTABLISHED)
tpop3d     418     root  240u  IPv4 0x30001568e18     0t697    TCP
mail:33276->mail:ldap             
 (ESTABLISHED)

I'm currently looking into the Solaris tuning aspects too, and I'll give
some feedback on that.
