Hi,

I was wondering what version of Aerospike Community are you using? Also just to confirm are you using the C client?

as_record_inita() internally uses alloca() to reserve record/bin space on stack. When this is done in a large loop, this can blow the available stack space of the calling function.

A simple solution is to move the as_record_inita() function outside of the loop:

as_record rectmp; as_record_inita(&rectmp,3);

for (unsigned long i=0;i<500000;i++) { char keybuf[100]={0}; snprintf(keybuf,sizeof(keybuf),“ro%010lu”,i); as_key keytmp; as_key_init_str(&keytmp,“test”,“demo-set2”,keybuf); as_record_set_int64(&rectmp,“bin1”,i); as_record_set_int64(&rectmp,“bin2”,i+10); as_record_set_int64(&rectmp,“bin3”,i+20);

if( AEROSPIKE_OK != aerospike_key_put(&as, &err,NULL,&keytmp,&rectmp) ) { fprintf(stderr,“err(%d) %s at [%s:%d]\n”, err.code, err.message, err.file, err.line); exit(-1); } }

Similar caution should be applied to as_query_select_inita(), as_batch_inita(), as_operations_inita() and as_scan_select_inita()
