Deadlocked App
Hello All -

We have a legacy C program running non stop on one of our servers, with several instances often running at once. Fairly regularly, one of the instances while stop outputting to the log file and will just deadlock/hang. They must be then 'kill'ed by myself.

When I gdb into one of the hung running processes, and enter the 'where' command I invariably get something like the following:

(gdb) where
#0 0x009f0402 in ?? ()
#1 0x00bdf1ce in __lll_mutex_lock_wait () from /lib/libc.so.6
#2 0x00b86abf in _L_mutex_lock_1965 () from /lib/libc.so.6
#3 0x00000000 in ?? ()

Does anyone recognise this? I'm sure it's indicative of a bug in the app but amn't sure how to track it down. Any suggestions would be very welcome.

Mark.

list-instances

asadmin-list-instances(1AS)					   User Commands				       asadmin-list-instances(1AS)

NAME

       asadmin-list-instances, list-instances - lists all the instances in the server

SYNOPSIS

       list-instances  [--user	admin_user]  [--password  admin_password]  [--host localhost] [--port 4848] [--domain domain_name] [--local=false]
       [--passwordfile filename] [--secure|-s]

       Use the list-instances to list all the instance in the server. The list-instances command can be run both locally and  remotely.   To  list
       remote  instances,  the named administration server must be running on the hostname and port number specified. The user authenticates using
       the password identified for the administration server.

OPTIONS

       --user		       administrative user associated for the instanace.

       --password	       administrative password corresponding to the administrative user.

       --host		       host name of the machine hosting the administrative instance.

       --port		       port number associated with the administrative host.

       --domain 	       name of the domain.

       --local		       determines if the command should delegate the request to administrative instance or run locally.

       --passwordfile	       file containing passwords appropriate for the command (e.g., administrative instance).

       --secure 	       if true, uses SSL/TLS to communicate with the administrative instance.

       Example 1: Using list-instances in local mode

       asadmin> list-instances --domain1 --local
       admin-server running
       server1 running

       Where: the server1 and admin-server instances for the domain1 domain is listed.

       Example 2: Using list-instances in remote mode

       asadmin> list-instances --user admin --passwordfile passwords.txt --host localhost --port 4848
       server1 [mayank:80] running

       Where: the server1 instance associated with the specified user, passwords, host, and  port  number  specified  is  listed  for  the  remote
       machine.
