IPsec problem between Azure and cisco 2900

Hi, im having problems with a site-to-site between an azure web server and my cisco 2900, wich randomly disconnects with the following debug message : 

 

Sep 22 19:16:32.831: IPSEC:(SESSION ID = 99405) still in use sa: 0x2471925C
Sep 22 19:16:32.831: IPSEC:(SESSION ID = 99405) (key_engine_delete_sas) delete SA with spi 0x343959A4 proto 50 for 186.153.138.2
Sep 22 19:16:32.835: IPSEC(send_delete_notify_kmi): not sending KEY_ENGINE_DELETE_SAS
Sep 22 19:16:32.835: %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel2, changed state to down

 

Im debugging ISAKMP, IPSEC and Crypto Engine. 

 

this messages are when the vpn stablishes again
