Hi! I'm trying to port a multithreaded C++ application (using the sendmail's milter library). It seems to work most of the time, but every once in a while hangs in the following line: size=read(pipe_io[1][0],iobuff,1024); I tried to ktrace it when it gets into this state, and ktrace.out remains empty. The process is in the ``piperd'' state, as reported by ps. Why would read(2) be hanging? The OS is 4.5-STABLE and I already recompiled the libc_r with the not-yet-MFCed patches to uthread_attr_setscope.c and uthread_dup2.c but that did not change a thing...
