Darkice core dump when used with oss driver in Centos 5.3

What steps will reproduce the problem?
1. I use darkice to capture from a Delta1010(sound card from M-Audio), and send 
to icecase2 for live streaming. Run up to 4 darkice instances, to capture from 
4 different analog inputs.
2. Darkice may cause kernel oops and core dump every serial hours.
3.

What is the expected output? What do you see instead?
Using dmesg, it maybe caused by oss_read

What version of the product are you using? On what operating system?
Darkice version is darkice-1.1
OS: Centos 5.3
OSS Driver: OSS 4.2 (b 2007/201209270042) (0x00040100) GPL
