Ann,

thanks for the reply.

Would you say then at this point it is unsafe to run a (or several)
multithreaded application which has/have 1 connection per thread on the same
machine running ibserver even if connecting using the remote interface (e.g.
myserver:c:\mydata.gdb)?

I ask because I have been running this way for quite some time, but with no
apparent problems yet.

thanks again.

rob
