The problem mentioned early for 3.7.1 remeains in 3.7.4.
Situation: Local Linux RedHat 6.2 is used to spool
jobs from central site and send it to the several
local print-servers {Axis 560, HP Jetdirect).
The problem with gdbm occurs when more then 100 jobs
at once are sent from central site. LPRng was compiled
from SRPM package. More detailed infos are at the end
of the mail.
