Perormance problems with 1.3.8 on Solaris 10

[Claus Sandmann]

Hello everybody,

I just installed CUPS 1.3.8 from source on a Solaris 10 machine. Printing works perfect, but every administration action, no matter whether using the webinterface or a command line tool like 'lpstat' is very slow and eats up 50% of cpu time. Sometimes the reaction is fast. Here is an excerpt of a truss of the lpstat:

access("/dev/random", R_OK)                     = 0
access("/dev/random", R_OK)                     = 0
open("/dev/random", O_RDONLY)                   = 4
pollsys(0x08046AA0, 1, 0x08046B18, 0x00000000) (sleeping...)
pollsys(0x08046AA0, 1, 0x08046B18, 0x00000000)  = 0
pollsys(0x08046AA0, 1, 0x08046B18, 0x00000000) (sleeping...)
pollsys(0x08046AA0, 1, 0x08046B18, 0x00000000)  = 0
pollsys(0x08046AA0, 1, 0x08046B18, 0x00000000) (sleeping...)
pollsys(0x08046AA0, 1, 0x08046B18, 0x00000000)  = 1
read(4, "C6 & ]B894 V OA01BD8FC8B".., 120)      = 120
pollsys(0x08046AA0, 1, 0x08046B18, 0x00000000) (sleeping...)
pollsys(0x08046AA0, 1, 0x08046B18, 0x00000000)  = 0
pollsys(0x08046AA0, 1, 0x08046B18, 0x00000000) (sleeping...)
pollsys(0x08046AA0, 1, 0x08046B18, 0x00000000)  = 0
pollsys(0x08046AA0, 1, 0x08046B18, 0x00000000) (sleeping...)

This list can be much longer.
This sleeping pollsys processes are the problem, because they don't appear when the reaction is fast.
Somebody any ideas?
