workman websocket問題
經(jīng)常出現(xiàn)一下這樣的錯誤信息，然后進(jìn)程正常退出
process_timeout:

這是業(yè)務(wù)處理超時導(dǎo)致的，當(dāng)沒有設(shè)置超時處理函數(shù)時或者超時處理函數(shù)返回為空時，businessworker進(jìn)程就會因此退出，從而導(dǎo)致businessworker與gateway的連接中斷， 所以從兩方面著手：
1、排查業(yè)務(wù)阻塞的原因；
2、設(shè)置處理超時回調(diào)以捕捉業(yè)務(wù)異常，避免進(jìn)程退出；?$businessworker->processTimeoutHandler(String $trace, Exception $exception)

iqige 2019-09-16根據(jù)錯誤棧的提示，不是應(yīng)該阻塞在檢查客戶端是否在線這一步嗎，我看了下sendAndRecv這個方法，已經(jīng)設(shè)置了超時。另外，有個問題，如果出現(xiàn)了busy進(jìn)程，strace -ttp pid 配合php start.php status -d ,追蹤是這樣子的：
11:17:54.169967 rt_sigreturn({mask=[]}) = 45
11:17:54.170040 recvfrom(6, 0x7f8dbea58018, 655350, 0, NULL, NULL) = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
11:17:55.167907 --- SIGUSR2 {si_signo=SIGUSR2, si_code=SI_USER, si_pid=18243, si_uid=0} ---
11:17:55.168112 rt_sigreturn({mask=[]}) = 45
11:17:55.168265 recvfrom(6, 0x7f8dbea58018, 655350, 0, NULL, NULL) = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
11:17:56.170834 --- SIGUSR2 {si_signo=SIGUSR2, si_code=SI_USER, si_pid=18243, si_uid=0} ---
11:17:56.170961 rt_sigreturn({mask=[]}) = 45
11:17:56.171059 recvfrom(6, 0x7f8dbea58018, 655350, 0, NULL, NULL) = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
11:17:57.171275 --- SIGUSR2 {si_signo=SIGUSR2, si_code=SI_USER, si_pid=18243, si_uid=0} ---
11:17:57.171352 rt_sigreturn({mask=[]}) = 45
猜測，是不是就是卡在檢查是否在線這一步？ -

這里的業(yè)務(wù)處理超時是針對 Events 的四個 onXXXX回調(diào)里的整體業(yè)務(wù)存在阻塞時而言的，這和sendAndRecv() 這個tcp連接的超時完全不是一回事， 反過來，根據(jù)題示棧信息也可以看出這個方法也是在onClose 回調(diào)觸發(fā)的，不管怎樣，這也只是相當(dāng)于整體業(yè)務(wù)里的一個局部子單元業(yè)務(wù)。
