** [tickets:#2043] log: ER no stream exists**
**Status:** review
**Milestone:** 5.1.1
**Created:** Mon Sep 19, 2016 05:20 AM UTC by Vu Minh Nguyen
**Last Updated:** Mon Sep 19, 2016 09:10 AM UTC
**Owner:** Vu Minh Nguyen
Logsv used following code to iterate all existing log streams:
```C
/* check existing streams */
num = get_number_of_streams();
stream = log_stream_get_by_id(--num);
if (!stream)
LOG_ER("No streams exist!");
while (stream != NULL) {
stream = log_stream_get_by_id(--num);
}
```
If we create 02 log streams, then delete them in the following order, above
code will run incorrectly.
1) Create streamA
2) Create streamB
3) Delete streamA
4) Reboot active node
We will get following in syslog:
> Sep 19 12:08:22 SC-2 local0.err osaflogd[453]: ER No streams exist!
