[Haskell-cafe] NetSnmp problem.

Hi, I am trying to use NetSnmp to get some information from my switch. And I met this problem. After initialize, I used snmpWalk to get some information, and dealed with it. Everything is fine. Then I sleep for 5 mins. SnmpWalk again. But this time, all asnValues were unsupported format, which broke my dealing process. Why? I am sure my switch and OID, bluh bluh bluh are correct. They worked in ruby script. -- 竹密岂妨流水过 山高哪阻野云飞
