| Summary | 0000188: pcp_proc_count truncates PIDs over 5 characters long | ||||
| Description | If the PgPool process IDs are over five digits in length then running pcp_proc_count will result in the PIDs being incorrectly reported. Specifically, each 6 digit PID will be truncated to 5 digits with the right most digit being removed. Although this is the output from the PgPool command (pcp_proc_count) it results in an error in PgPool admin as the "Process Info" output will error (e1005 - pcp_proc_info command error occurred) - because the PID passed to the command is incorrect and results in a "BackendError". We are running pgpool-II 3.4 on Centos 7.5.1511 (Core). | ||||
| Steps To Reproduce | The PgPool PIDs need to be over 5 digits to show the bug but then this can be reproduced consistently using: $ pcp_proc_count 10 localhost 9898 apgpooluser 'somepassword' 14230 13921 14292 14191 14208 ... However the reported PIDs will all be incorrect and shortened by one digit as shown by: $ ps -ef | grep 14230 root 142306 24222 0 17:26 ? 00:00:00 pgpool: wait for connection request The PID is actually 142306 and not 14230. Similarly... $ ps -ef | grep 13921 root 139210 24222 0 16:58 ? 00:00:00 pgpool: wait for connection request Again, the PID is 139210 and not 13921 | ||||

Interesting. How large is your system's pid max? (/proc/sys/kernel/pid_max) |
|
|
pid_max is 147456 |
|
|
pcp_proc_count thinks that 5 digit is enough for process ids. Pengbo is working on fixing it. |
