That could well be because you changed TCP_TMR_INTERVAL.

It's not supposed to be changed. If it was, it would be in opt.h, not in tcp_priv.h! If guess you want to have faster retransmission, but messing with TCP is not the correct way to achieve that. > sys_check_timeouts() is called every 10ms (according to google search, > sys_check_timeouts() should be called instead of tcp_tmr(), right?)
