LPC 1.2.0 Linux failed to access shared memory
Best Answer
-
The shared memory key may be used by another process. You can verify the shared memory key used by LPC in the lpc.cnf.
!!
!! Shared memory configuration
!!
*maxSemaphores : 6
*admin*maxClients : 10
*lpc*admin*semaphoreKey : 90
*lpc*admin*sharedMemoryKey : 90
*lpc*admin*sharedMemorySize : 1000000
*lpc*admin*enableChildStats : False
*lpc*admin*enableRootStats : True
*lpc*admin*enableMemoryStats : TrueYou can run the ipcs command to verify the used shared memory key.
[root@1a0c6c8cf009 config]# ipcs
------ Message Queues --------
key msqid owner perms used-bytes messages
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x0000005a 0 root 664 1000432 1
------ Semaphore Arrays --------
key semid owner perms nsems
0x0000005a 0 root 666 60x0000005a is a hexadecimal number of 90.
You can change the number of sharedMemoryKey in the LPC configuration file.
Otherwise, you may verify if another LPC process is running on the machine.
