[ECOS] Delays while network processing

Hello,

I am using the ARM7 SNDS port from Grant Edwards. I don't use ecos 2.0.

In my application there are several threads and each have some TCP 
connections. I'm using pthreads.
Sometimes the network transfer stops for many seconds or even minutes. This 
happens sometimes on all threads, but sometime only on one thread and it 
could happen while data is incoming or/and data is outcoming.
The threads have the same priority (15). But while the delay the scheduler 
seems to be in idle state.
The problem happens more often if there is more network traffic in my theads, 
but sometime is also there, if I use a simple telnet menu (can't be much 
traffic).

Does anybody have any idea?

Roland
