Error on secondary bluetooth connection

[gunar.kroeger]

When connecting a secondary bluetooth device to the esp32 I get an error message:

(768946) SPP: ESP_SPP_DATA_IND_EVT len=3 handle=3
D (768946) SPP: primary channel data:
I (768946) SPP: start processing 01

I (768956) SPP: finnished processing 01
I (768956) SPP: ESP_SPP_WRITE_EVT 0
E (779396) BT_OSI: alarm_set failed to start timer, err 0x103

I (780036) SPP: ESP_SPP_SRV_OPEN_EVT handle=641
D (780036) SPP: secondary channel open: 641
I (783586) SPP: ESP_SPP_DATA_IND_EVT len=3 handle=3

Is this a bug or am I supposed to do something special when connecting more than one device at once?
Everything apart from this message seems to work

Thanks
