SQL*Plus With Instant Client 10.2.0.1 Hangs, When System Uptime Is More Than 248 Days
metalink上的给出的答案是

Applies to: SQL*Plus – Version: 10.2.0.1.0
Linux x86
SymptomsTrying to invoke SQL*Plus hangs when machine uptime reaches 248 days.

Database connection is not relevant as the ’sqlplus’ executable itself hangs with or without connection information. It hangs regardless of what parameters are passed in. For example:

sqlplus -V

However, the hang does not reproduce with Instant Client version 10.1.0.4

Generating a stack trace using gdb debugger shows:

#0 0×0048a0dd in times () from /lib/tls/libc.so.6
#1 0×01884599 in sltrgatime64 () from ./libclntsh.so.10.1
#2 0×0137d70f in kghinp () from ./libclntsh.so.10.1
#3 0×00f86b47 in kpuinit0 () from ./libclntsh.so.10.1
#4 0×00f85e7a in kpuenvcr () from ./libclntsh.so.10.1
#5 0×01051b5e in OCIEnvCreate () from ./libclntsh.so.10.1
#6 0×0099787e in afidrv () from ./libsqlplus.so
#7 0×009702b9 in safimTerminate () from ./libsqlplus.so
#8 0×0098c246 in afidrv () from ./libsqlplus.so
#9 0×080486f6 in main ()

Running STRACE tool shows:

$ strace /oracle/home/bin/sqlplus -V 2>&1 |less

old_mmap(NULL, 385024, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0×41794000

access(“/usr/local/UD/conf/sqlnet.ora”, F_OK) = -1 ENOENT (No such file or directory)

times(NULL) = -1825782405
times(NULL) = -1825782405
times(NULL) = -1825782405
times(NULL) = -1825782405
times(NULL) = -1825782405
times(NULL) = -1825782405
times(NULL) = -1825782405

It is looping on the times() function.

In addition to sqlplus, it has been reported that the netca and dbca tools also hang.
