 |
|
Hello,
On several of my computers, I'm running into never-ending eclean-dist processes.
They run properly, cleanup what should be, display the list of « installed but unavailable packages », and then wait forever.
On a server rebooted 5 weeks ago, I had 5 eclean-dist « running but waiting », one per week (eclean is called through cron.weekly). Same thing if clean-dist is started manually.
Any idea about what's happening, and how to solve it ? Emerge stil runs ok, nothing seems to be broken anywhere, just those processes lingering...
Thanks. |

How is it being run with cron? Is it being run in such a way that expects user input? Are there no mail messages to the user or root about problems?

A simple bash script that calls eclean-dist. Nothing fancy, has been running that way since a long time.
No emails are sent, the process just seems to wait for « something » (no CPU usage whatsoever).
The same problem arises if I call eclean-dist from the command line, so I do not think it is related to cron. |

| Is there anything in dmesg suggesting that the drive is not responding? When a process hangs like this, can it be interrupted by SIGINT? What does strace say is the last call it makes? |

Hi,

The computer is perfectly working : nothing weird in dmesg, the drives are ok. The process can be stopped (^C, sigint, anything goes). As for strace, here the end of the log :
| Code: | write(1, " \33[33;01mcross-armv7"..., 90) = 90
write(1, " \33[33;01mcross-armv7"..., 83) = 83
write(1, " \33[33;01mcross-armv7"..., 90) = 90
write(1, " \33[33;01msys-kernel/"..., 67) = 67
write(1, " \33[33;01msys-kernel/"..., 67) = 67
write(1, "\n", 1) = 1
wait4(28636, 0x7ffcead5e854, WNOHANG, NULL) = 0
wait4(28636, 0x7ffcead5e854, WNOHANG, NULL) = 0
getpid() = 28632
wait4(28636, |
The write are the messages telling about installed but unavailable packages. The 28636 process is :
| Code: | 28629 pts/3 S+ 0:12 strace eclean-dist --verbose
28632 pts/3 S+ 0:11 /usr/bin/python3.12 /usr/lib/python-exec/python3.12/eclean-dist --verbose
28636 pts/3 S+ 0:00 /usr/bin/python3.12 /usr/lib/portage/python3.12/socks5-server.py /var/tmp/portage/.portage.28632.net.sock |
Not quite sure what it may mean. |

When I kill (with ^C) the eclean-dist process from my previous message, I get this :
