Not here.

We have two different settings for these depending on the IOC's client load:
125, 400, 50, 25, 25, 25 and 256*4 for the smaller IOCs, and
250, 400, 50, 50, 25, 25 and 1024*2, 512*2 for the larger ones.
Note that in recent vxWorks 6.x releases they've replaced the network stack
*again*, and the new one goes back to the original configuration of just
setting the maximum amount of RAM the stack is allowed to use.

replacing it with something that almost works, but costs less.
