Folks

I have ace setup as active/standby . What we are noticing is on primary ace we can ping servers but on secondary we can't ping some servers

See below

From Primary ACE:

EWDC-T1ACE12-1/Education# ping 172.28.8.84

Pinging 172.28.8.84 with timeout = 2, count = 5, size = 100 ....

Response from 172.28.8.84 : seq 1 time 0.243 ms

Response from 172.28.8.84 : seq 2 time 0.434 ms

Response from 172.28.8.84 : seq 3 time 0.221 ms

Response from 172.28.8.84 : seq 4 time 0.203 ms

Response from 172.28.8.84 : seq 5 time 0.190 ms

5 packet sent, 5 responses received, 0% packet loss

I also ran some debug . Look for 172.28.8.84 in the file attached. Any ideas what could be wrong?

Hi,

If found this in your trace:

2009 Apr 29 23:00:24.579199 arp/icmp mgr: (ctx:1)ICMP echo request (len 108 id 8193 seq 1) to 172.28.8.84

2009 Apr 29 23:00:24.579233 arp/icmp mgr: (ctx:1)icmp_transmit_pkt: Transmit packet entered length = 100

2009 Apr 29 23:00:24.579282 arp/icmp mgr: (ctx:1)icmp_transmit_pkt: Memsetting data length = 100

2009 Apr 29 23:00:24.579406 arp/icmp mgr: (ctx:1)icmp_transmit_pkt: send_traffic: error -11 from ed_write_pkt: Resource temporarily unavailable

Could you perform a reboot of the standby ACE?

Never saw this problem. What version are you using?
