CUCM Syslog Message ISSUE (kernel: Exceeded hashlimit)

Hello.

Our Customer using CUCM 9.0 (PUB :1 , Sub : 4) and 4 Voice Gateway Cisco 3945 (16 E1 PRI per each Gateway)

CUCMs have problem with syslog messages.

I saw these messages in rtmt syslog

- kernel:  Exceeded hashlimit IN=bond0 OUT= MAC=34:40:b5:d5:63:e8:1c:e6:c7:52:44:40:08:00 SRC=130.1.254.27 DST=130.1.13.11 LEN=204 TOS=0x00 PREC=0x00 TTL=246 ID=19646 PROTO=UDP SPT=19200 DPT=30546 LEN=184

kernel:  Exceeded hashlimit IN=bond0 OUT= MAC=6c:ae:8b:67:1a:28:bc:16:65:12:99:7f:08:00 SRC=130.1.254.27 DST=130.1.14.13 LEN=204 TOS=0x18 PREC=0xA0 TTL=253 ID=42621 PROTO=UDP SPT=26694 DPT=26842 LEN=184

What's the problem with these messages ?

And how can I solve this problem

Thanks.

I used to have the same problem, it was a sip trunk against to one CME, just reset the sip trunk in CUCM it fixed the error. it is because the end poing is sending a lot of requests to CUCM
