Hi all.<div><br></div><div>I'm testing pgpool-II to help me to create a robust solution to my company. I've spent a day testing it and I get stucked after a while, pgpool-II stopped to work without reason.</div><div>
<br></div><div>After debugging a while I've found that pgpool-II worked when I called it using "-n" (do not detach). After that, I tried a strace in the process and compared both outputs.</div><div><br></div>
<div>When I start pgpool without flags, I got this strace fragment:</div><div><br></div><div><div>4177 open("/etc/pgpool-II-91/pool_passwd", O_RDWR) = 3</div><div>4177 semget(IPC_PRIVATE, 3, IPC_CREAT|IPC_EXCL|0600) = 6520852</div>
