Hi,

In one application I had problems with Csound native OSCsend (not using liblo) - when sending many messages, at some point it ended with error:

with OSCsend_lo it worked.

I made a test csd and discovered that it only happens when OSCsend is called at init time. If it is called at k-time there is no such problem.

See the attached file -

instr 3 (OSCsend on init time) fails with around 90..100 calls in the loop.

instr 2 works (both OSCsend and OSCsend_lo called on first k-cycle)

I found solution for myself but if there is something to check in the code, maybe it is helpful.

Tested on Linux, Csound version 6.13 beta (double samples) May 21 2019
