Is there a command that will display the current utilization percentage of the network streams "strthresh" value? Is there a way to determine what processes are consuming this resource?

I have a P630 with 2GB of memory that primarily serves as a public webserver. I'm running AIX 5.2 ML6. The server appears to have a memory leak associated with the buffer space used for streams connections.

My problem is every month or two (or sometimes less than a month), the server reaches the strthresh value (set to the aix default of 85) and will not open new non-root TCP streams connections. The only way to resolve this problem is to connect as root to the local console and either:

1) increase the value of strthresh (which only buys additional time until the new strthresh value is reached)
2) reboot the server and start the whole cycle again.

Any help or ideas are appreciated.

Thanks!
