I also installed this patch on the server that showed the problem. After
12 hours:
        217612 SYN cache entries added
                0 hash collisions
                202657 completed
                0 aborted (no space to build PCB)
                837 timed out
                0 dropped due to overflow
                0 dropped due to bucket overflow
                14045 dropped due to RST
                0 dropped due to ICMP unreachable
                216774 delayed free of SYN cache entries

Memory resource pool statistics
Name        Size Requests Fail Releases Pgreq Pgrel Npage Hiwat Minpg Maxpg Idle
synpl        280   217996    0   217993    21    19     2     4     0   inf    1

So this seems to work fine. I'll wait a few more days
before commit.

thanks for the help !
