Hi! I sent this note to "java-port," but haven't heard anything. Sorry if
this is redundant. Any advice would be greatly appreciated!
I have a console java app running under JDK 1.8 on FreeBSD 3.3 stable. I've
tried with and without TYA and it has the same problem. The app works fine
most of the time, but at seemingly random times it simply stops progressing.
That is, the task is still there soaking up CPU but it appears stuck. A
truss shows the following output (which repeats itself like a hard loop):
SIGNAL 14
SIGNAL 14
SIGNAL 14
syscall sigsuspend(0x0)
errno 4 'Interrupted system call'
syscall sigprocmask(0x1,0x0)
returns -65793 (0xfffefeff)
syscall sigprocmask(0x3,0x0)
returns -65793 (0xfffefeff)
syscall gettimeofday(0x2940de18,0x0)
returns 0 (0x0)
syscall setitimer(0x0,0x2940de00,0x0)

returns 0 (0x0)
syscall sigreturn(0x2942edbc)
errno 4 'Interrupted system call'
syscall sigprocmask(0x1,0x0)
returns 0 (0x0)
Is there anything I can do to help debug this?
Regards,
Rick
