have a clue about what is going on.
Any ideas? Thanks for your time.

Subject: Weird locking issue with makemap, sendmail on a 4.1-R SMP.
To: [EMAIL PROTECTED]
Date: Fri, 15 Sep 2000 15:07:11 -0300 (ART)
Hello:
I'm having a weird problem with my SMP 4.1-RELEASE mail server:
CPU: Pentium III/Pentium III Xeon/Celeron (731.02-MHz 686-class CPU)
Origin = "GenuineIntel" Id = 0x683 Stepping = 3
Features=0x383fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA
,CMOV,PAT,PSE36,MMX,FXSR,XMM>
real memory = 536854528 (524272K bytes)
First thing I noticed was that newaliases was getting hung.
Further investigation showed the problem was
~majordom/aliases.majordom.db
Running makemap hash ~majordom/aliases.majordom <
~majordom/aliases.majordom hunged also.
A fstat showed only sendmail has this file open, and for
reading only.
A ktrace shows:
[...]
87185 makemap CALL open(0xbfbff658,0x622,0x1a4)
87185 makemap NAMI "aliases.majordomo.db"
[a lot of time... sent kill]
87185 makemap PSIG SIGINT SIG_DFL
aliases.majordom.db ends with 0 bytes. Removing the file
solves the problem.
Sometimes same thing happens with virtusertable and similar
aliases-related files.
Today the same happened with access.db. Lsof showed
sendmail 52975 root 7rR VREG 109,196608 0 35980 /etc/mail/access.db
which means sendmail has the whole file locked for reading.
Doing a ps -axl shows lockfs state and a sleeping process
(waiting for a lock, I guess).
Any ideas? Thanks in advance!
