Re: Exceeded deadline by 16ms
Hi,

Thanks for quick reply!
I am seeing sequence of "exceeded deadline" message then  connection timed
out error messages.
My code has some usleep() calls, when a sequence of zoo_get and zoo_set
returns ZBADVERSION error due to race condition,
it invokes usleep() for random time(between 5ms to 100ms) and then retry
the same operation. Does this may be cause any issues?

Please find following log dump:
