On my > consumer side, the process seems to run with very high CPU usage. I turned on > HPROF, and it's showing that 75% of the CPU usage is going to Java's NIO > EPoll/select calls. > There are supposedly work arounds that Mina and a few others employ. This > seems like more of a ZK bug- have you guys seen this before? > Any ideas? -- This message is automatically generated by JIRA.
