Hi Colin,
As you indicated it seems that an actual allocation problem occurred on:
syscall table list zmalloc: Cannot allocate memory (in syscall_table_list() at
syscall.c:291)
>From the code:
/*
* Allocate at least the number of total syscall we have even if some of
* them might not be valid. The count below will make sure to return the
* right size of the events array.
*/
events = zmalloc(syscall_table_nb_entry * sizeof(*events));
if (!events) {
PERROR("syscall table list zmalloc");
ret = -LTTNG_ERR_NOMEM;
goto error;
}
syscall_table_nb_entry is assigned in syscall_init_table.
Could you link the full sessiond log and strace log? Also if possible
determine the value of syscall_table_nb_entry?
Cheers
