I recently discovered that my MidnightCommander takes around 40 seconds for every startup and the same goes for McEdit.

I access my machine only via ssh and of course I'm not logging in as root, only to prevent the questions.

I did an strace and it puts out two system calls that take around 20 seconds:

poll([{fd =3, events=POLLIN}], 1, -1) = 1 ([{fd=3, revents=POLLIN}]) select(5, [4], NULL, NULL, NULL) = 1 (in [4])

Unfortunately I don't have the heck of a clue what these calls are, any hints or help would be appreciated, thanks in advance!

Update: If I do a sudo mc it works as usual, only with my accout it does take that long.

Solution: The solution is simple, I had X11 forwarding in Putty enabled, after deactivating it everything works like a charm. Strange, but anyway, it works again.

Thanks for your answers!

  • You should ask them about this via the mail list or a bug report. I've been using mc (but never the internal editor) constantly, everywhere I work, for years and years, and never seen it take more than a second (two would indicate a very busy machine) even remotely on a wimpy little system. Of course first make sure the system isn't constantly busy... – goldilocks Apr 23 '14 at 8:51
  • Thanks, I will if no solution pops up. At least I know it's not about the busyness, the machine has way enough resources left for this little task! – Mäx Müller Apr 23 '14 at 9:10
  • You need to scroll back in the trace and find what is opened on that file descriptor. – Gilles 'SO- stop being evil' Apr 23 '14 at 21:24

I have had similar problem. Check if your hostname is properly resolved to IP address. If not, try to add your hostname to /etc/hosts eg.: myhostname myhostname.mydomain

  • I'm a bit confused, the /etc/hosts says myhost Can this be right? Sounds wrong to me, but I don't know. – Mäx Müller Apr 23 '14 at 9:12
  • It's ok. loopback has address network – Artur Szymczak Apr 23 '14 at 9:15
  • Alright, so this is not the solution. I updated the question because I discovered that everything is fine if I call mc via sudo, any ideas? – Mäx Müller Apr 23 '14 at 9:17
  • Could you post your strace on pastebin? And another strace with -c – Artur Szymczak Apr 23 '14 at 9:21
  • strace -c: pastebin.com/SxQUrXP2 strace:pastebin.com/pFbiWGYC – Mäx Müller Apr 23 '14 at 9:33

I have a similar problem when X forwarding is on, but X server is not running on my client. You have to use the -X or --no-x11 command line parameter with mc to prevent waiting for a timeout (which may be only 2 seconds, not 40).
