SocketCAN recovery from buffer overflow CAN_ERR_CRTL_RX_OVERFLOW

Question

I write an application in C/C++ which uses SocketCAN. Under some conditions I can generate an buffer overflow error CAN_ERR_CRTL_RX_OVERFLOW on my system. An ip command shows growing number of overflow errors.

ip -details -statistics link show can0
2: can0: <NOARP,UP,LOWER_UP,ECHO> mtu 16 qdisc pfifo_fast state UP mode DEFAULT group default qlen 10
    link/can  promiscuity 0 minmtu 0 maxmtu 0 
    can state ERROR-WARNING (berr-counter tx 0 rx 0) restart-ms 100

    639        128      0       0       0       0 

Moreover, at this state the operating system is getting laggy due to high cpu usage by following system processes also after killing my application:

• [irq/61-5a001000]
• [ksoftirqd/0]
• [kworker/u4:0+ev]

I would like to programmatically recover from this error state and somehow flush the buffer taking packet loss into account.
