Can't create output

Hi there,

We have been using procmail for a while now on a single machine. We 
recently decided to change to a load balance situation and use the 
Maildir format over NFS.

We ran into an issue with this however. Every few minutes we would get 
a line in our sendmail log like this:

Oct 10 18:35:32 smtp4 sendmail[84188]: h9B1ZFw83970: 
to=<[email protected]>, delay=00:00:16, xdelay=00:00:00, mailer=local, 
pri=662847, dsn=5.0.0, stat=Can't create output

After doing some tracking I noticed a bug in the retry mechanism of the 
writefolder routine. This part:

  strcpy(chp2,maildirnew);
  chp2+=MAILDIRLEN;
*chp2++= *MCDIRSEP_;
strcpy(chp2,chp);

is executed every time through the loop. Once is fine but if a retry is 
actually executed then maildirnew is appended for the number of 
retries. I just did this:

               if (retries == MAILDIRretries)
                 {
                 strcpy(chp2,maildirnew);
                 chp2+=MAILDIRLEN;
                 *chp2++= *MCDIRSEP_;
                 strcpy(chp2,chp);
                 }
and that fixed one issue.

Thanks,
